HVAC for Valley Heat and Mountain Cold

Lumby's Monashee foothill location creates a specific HVAC challenge. The valley traps summer heat on 35°C+ days that build through July and August with less breeze relief than lakeside communities get. Winters are among the coldest in the North Okanagan, with Creighton and Trinity Valley properties regularly seeing -25 and colder. Most rural homes run propane furnaces, and many older properties lack ductwork entirely. The HVAC system needs to handle both extremes honestly.

Stevenson Mechanical installs and services HVAC across Lumby, Creighton Valley, Trinity Valley, and Mabel Lake Road with central AC where ducts exist, ductless mini-splits for farmhouses and cabins that don't, cold-climate heat pumps with proper propane furnace backup, and ductwork repair. Sized against real Lumby climate data, not Kelowna's milder numbers or generic provincial templates.

  • Central AC installs & replacements
  • Cold-climate heat pumps with furnace backup
  • Ductless mini-splits (no-duct homes)
  • Propane furnace repair & high-efficiency installs
  • Ductwork sealing & redesign
  • HRVs & smoke filtration
What We Handle

HVAC for Lumby & the Valleys

  1. Central Air Conditioning

    For Lumby homes with ductwork that are sized for real valley heat loads trapped between Monashee slopes.

  2. Cold-Climate Heat Pumps

    Summer cooling and shoulder-season heating in one unit. Lumby's winters demand gas or propane furnace backup, we pair it correctly.

  3. Propane Furnaces

    Most Creighton and Trinity Valley homes run propane. Repair, replacement, and annual tune-ups sized for -25 lows.

  4. Ductless for Rural Homes

    Older farmhouses, Mabel Lake cabins, and homesteads without central ducts with mini-splits deliver real comfort without demolition.

  5. Smoke Filtration

    Lumby valley traps wildfire smoke in summer. HEPA and carbon filtration built into the HVAC system, not bolt-on room units.

  6. Seasonal Maintenance

    Spring cooling, fall heating. Priority routing to Lumby so rural communities aren't last on the schedule.

How It Works

HVAC for Both Extremes

  1. Whole-Property Assessment

    We look at the entire Lumby property involves insulation, elevation, valley position, propane supply, not just the old equipment.

  2. Honest Recommendation

    Central, ductless, heat pump? We pick what fits your home, valley exposure, and budget! Not the unit with the best margin.

  3. Itemized Written Quote

    Equipment, install, ductwork, electrical, propane, permits we make every line item on an invoice separate.

  4. Clean Install

    HVAC, electrical, gas provided by one team, one schedule. Critical when rural properties can't afford multiple contractor visits.

  5. Commissioning + Service

    System started properly, airflow balanced, first seasonal tune-up booked.

Why Stevenson

Why Lumby Picks Us for HVAC

Valley-Specific Sizing

Lumby's valley traps both summer heat and winter cold differently than lakeside communities. We size for the real microclimate.

Propane Furnace Specialists

Most Lumby acreages run propane. We install and service propane furnaces with the same expertise and code compliance as natural gas.

Smoke Filtration Experience

Valley smoke events are worse in Lumby than on the lake. We integrate filtration into the HVAC system properly.

Multi-Trade In-House

HVAC, electrical, propane gas fitting performed by one team, one warranty. No sub-trade coordination on rural drives.

Shadd and his team are absolutely wonderful and did a great job. I needed a basement sink plumbed and new washer dryer hookups and they were able to get it done in short order, kept everything tidy and were super easy to deal with. They knew my budget and worked with me to stay within it and gave me everything I needed. They are very professional, skilled and their prices are more than reasonable. I would highly recommend them to everyone!

HIGHLY RECOMMENDED BY US! 4 weeks ago, our hot water and air conditioning quit working on the same day! I called and spoke with the AMAZING Denise, she had Alex out at our shop within the day and he had everything diagnosed and parts ordered, not long after the first appointment, he had our hot water back in working order and then our A/C was repaired after that! Anytime we have had any issues, they have been very prompt to show up on the same day and Alex fixed it all! Such amazing and friendly services! You all have a forever client with Integra Tire and our team moving forward! Thank You!

Plumbing problems are never fun, but we appreciated how Stevenson Mechanical handled the replacement of our sump pump --from booking the appointment to the on-time arrival of our plumber and his friendly, competent service (which included persevering through some unexpected issues). Thank you for your expertise and excellent service!

This company is great! We needed to have our air conditioning unit disconnected and moved temporarily as we were getting our backyard patio redone. They were able to accommodate our last minute request, they completed the work quickly and got our unit reconnected just in time to beat the heat ! I would highly recommend them!
